  Casting this spell shifts the caster (and all of her equipment), along wil all of her allies within 80 feet, into the ethereal plane until the caster elects to cancel the spell. While ethereal, the caster is incorporeal and invisible with regard to creatures on the material plane, but can interact physically with other ethereal creatures.
